An unprivileged network attacker could gain system privileges to provisioned Intel manageability SKUs: Intel Active Management Technology AMT and Intel Standard Manageability ISM. An unprivileged local attacker could provision manageability features gaining unprivileged network or local system...

CVE-2015-4692

The kvmapichasevents function in arch/x86/kvm/lapic.h in the Linux kernel through 4.1.3 allows local users to cause a denial of service NULL pointer dereference and system crash or possibly have unspecified other impact by leveraging /dev/kvm access for an ioctl call...

Null pointer dereference

The kvmapichasevents function in arch/x86/kvm/lapic.h in the Linux kernel through 4.1.3 allows local users to cause a denial of service NULL pointer dereference and system crash or possibly have unspecified other impact by leveraging /dev/kvm access for an ioctl call...

CVE-2015-4692

CVE-2015-4692 affects the Linux kernel’s KVM code: in arch/x86/kvm/lapic.h, the kvm_apic_has_events() function may dereference a NULL pointer via an ioctl to /dev/kvm, enabling a local attacker to cause a denial of service (system crash). The description indicates the issue exists through kernel ...

Ubuntu 12.04 LTS : linux vulnerabilities (USN-2417-1)

Nadav Amit reported that the KVM Kernel Virtual Machine mishandles noncanonical addresses when emulating instructions that change the rip Instruction Pointer. A guest user with access to I/O or the MMIO can use this flaw to cause a denial of service system crash of the guest. CVE-2014-3647 A flaw...

Ubuntu 14.10 : linux vulnerabilities (USN-2421-1)

A flaw was discovered in how the Linux kernel's KVM Kernel Virtual Machine subsystem handles the CR4 control register at VM entry on Intel processors. A local host OS user can exploit this to cause a denial of service kill arbitrary processes, or system disruption by leveraging /dev/kvm access...
